The Elcometer 355 Modular Coating Thickness Gauge is a hand-held dry film thickness gauge supplied without a probe (part numbers A355---S Standard and A355---T Top), so the operator selects the probe module best suited to the application. Coating thickness directly affects how well a paint or protective system performs; too thin and it fails early, too thick and it wastes material or cracks, so accurate measurement is central to coatings inspection and quality control.
The Elcometer 355 Modular Coating Thickness Gauge measures to an accuracy of plus or minus 1% or 1 micron, whichever is greater, and reads at 40 readings per minute. Probe modules cover ferrous and non-ferrous substrates and are interchangeable, each supplied with calibration foils. The Standard model holds 5,000 readings in pre-set batches while the Top model holds 10,000 readings in up to 200 individually calibrated batches. Full statistical analysis is available, including mean, standard deviation, number of readings and the highest and lowest values, and every reading carries a date and time stamp. Data is output via RS232 to a PC, data-logger or printer, and ElcoMaster software is supplied. The rugged aluminium case suits demanding environments, and the Elcometer 355 Modular Coating Thickness Gauge runs from AA alkaline or rechargeable cells for a minimum of 40 hours.
The Elcometer 355 Modular Coating Thickness Gauge can be used in accordance with a wide range of standards including ISO 2360, ISO 2808, ASTM B 244, ASTM B 499, ASTM D 7091, SSPC PA 2 and the IMO MSC.215(82) and MSC.244(83) ballast tank coating standards. This product is discontinued. The Elcometer 355 Modular Coating Thickness Gauge is supplied by BAMR, South Africa's authorised Elcometer distributor.

When to use the Elcometer 355 Modular Gauge
Reach for this gauge when one hand-held instrument has to measure dry film thickness across many applications by swapping probe modules, and the readings have to be logged and reported. It suits inspectors and labs that need traceable, standards compliant data.
- 1Interchangeable probe modulesSelecting the right probe module for each application lets one gauge cover a wide range of coatings and substrates instead of buying separate instruments.
- 2Logs, analyses and outputs dataMemory up to 10,000 readings in batches with full statistics and RS232 output means inspection data can be stored and sent to PC or printer for reporting.
- 3Broad standards complianceConformance to ISO, ASTM, SSPC and IMO methods among others supports thickness readings that have to satisfy a specification or marine coating requirement.
- 4Rugged for tough environmentsThe aluminium case and 0 to 50 degree operating range suit demanding site conditions rather than bench only use.

Frequently asked questions
What is the difference between the Elcometer 355 Standard and Top models?
The Standard model (A355---S) stores up to 5,000 readings in pre-set batches. The Top model (A355---T) stores 10,000 readings across up to 200 individually calibrated batches. Choose the Top model if you need greater storage capacity or batch calibration flexibility.
I need to measure coatings up to 5mm thick. Which probe scale should I use?
Use a Scale 2 probe, which measures 0 to 5mm with accuracy of ±1% or ±5μm. Scale 2 probes are available in Telescopic and Standard designs to suit different installation constraints.
What measurement accuracy does the Elcometer 355 provide?
Accuracy is ±1% or ±1μm on Scales 1, 4, and 5. Scale 2 offers ±1% or ±5μm. Resolution varies by scale and measurement range, from 0.1μm at lower ranges to 5μm at higher ranges.
How do I transfer the readings from the gauge to my computer?
The Elcometer 355 outputs data via RS232C serial or parallel connection using a D25 type connector (female). Data can be sent to a PC, data-logger, or printer as required.
What are the minimum space and sample size requirements for the different probes?
Minimum headroom ranges from 18mm to 90mm depending on probe type. Minimum sample diameter ranges from 3mm to 18mm. Specific requirements depend on the scale and probe design you select.
